Application December 23, 1944, Serial No. 569,553

This invention relates to a method and means for utilizing the flow of exhaust gases and the like.

An object of the present invention is to utilize the draft caused by suction of escaping gases for the purpose of increasing the force developed in the process in the course of which the gases were produced, of providing or furthering the circulation of a, heating or Ventilating medium, and for a variety of other purposes.

' Other objects of the present invention will be- 1 Claim. (Cl. 237-123)y come apparent in the course of the following specication.

In accomplishing the objects of the present invention it was found desirable to provide a partly enclosed chamber at the mouth of the gas now. This chamber may consist of a sleeve of substantially larger diameter than an exhaust pipe and supported surrounding the same and extending for a substantial distance to the front and rear and to the wingtips and rudder thereof for the purpose of deicing same.

The invention will appear more clearly from the following detailed description when taken in consideration with the accompanying drawings showing, by way of example, a preferred embodiment of the inventive idea.

In the drawings:

Figure 1 is -a view of the invention applied to an automobile;

Figure 2 is a lateralsection along the line 6-6 of Figure 1.

The drawingshows the invention applied to an automobile to heat the same and cool the exhaust pipe.l The automobile 3| has the usual motor 32, exhaust pipe 33, and muler 34. Around the exhaust pipe 33 and muler 34 is supported the hot air heater 35 comprising a plurality of heat exbe utilized as a motive power for the circulation of heating or Ventilating medium.V In the case of moving vehicles, this suction may be combinedl with' the'suction caused by the movement of the vehicle. Centrifugal force may be utilized for the same purpose in the case of airplane propel- 1ers and similarly revolving parts.

A bazooka projectile may be provided with a cylindrical sleeve open at both ends, and gases escaping from the exhaust pipe mouth will suck rearward the air in the sleeve forward of the pipe mouth. This causes a backward sucking of air into the sleeve inlet, increasing the speed and range of the projectile.

In la second embodiment, a similar sleeve was mounted on an automobile exhaust pipe extending forward and rearward of the mouth thereof.

'The above mentioned suction was used to draw air from the car interior and pass it through a series of heat exchanging fins mounted on the pipe, cooling the pipe, heating the air, which was further drawn through various heating pipes in the car interior before being drawn out with the exhaust gases.

In a third embodiment, a similar mounting and heating arrangement was availed of to lead hot air to the leading edges of an airplane propeller changing vanes or fins 35 connected to the muffler 34. Heater 35 has a cylindrical outer wall 35B and a semi-cylindrical inner wall 35A, the space between the two walls forming a passage 35C through the heater but having only boundary contact therewith, as no fins 36 extend beyond wall 35A. The vanes 36 can be mounted directly on the exhaust pipe 33 if no muffler is used or if any other consideration so dictates.

The exhaust pipe 33 terminates in a mouth 3T and supported surrounding the exhaust pipe 33 is the sleeve 38 having a rear portion'39 extending to the rear of or beyond the mouth 31, and a longik42 formed in the foremost portion thereof and communicating directly with the outside air through scoop or funnel 43 and valve 44. The second inlet 45 communicates with passage 35C within the heater 35 and through it and advanced pipe 46 and valve 41 with the -outside air, the mouth 48 of pipe 46 being located at a point in advance of the heater 35.

The third inlet to portion 4| is an opening 49 into suction pipe 50, which communicates through a forward circuit 5| of pipe with the heater 35 through pipe 52. The circuits 5| and 53 have been indicated diagrammatically only, it being understood that they may contain radiators and have fansassociated with them, as desired, in order to heat the car, defrost the windshield and the like. Suction pipe 50 also communicates with rear circuit 53 of pipe leading to pipe 52 and heater 35. Heater 35 has an inlet opening 54 communicating with the interior of the vehicle through three-way Valve 55 and pipe 56, and communicating with the outside air through valve 55 and scoop 56A.

The operation of this embodiment of the invention is that exhaust gases moving rearwardly in rear portion 39 of sleeve 38 create rearward suction and rearward movement of air in forward portion 4l of sleeve 38. The least effect of the installation is observed with valves 41 and 55 closed and vaiveflil fopen. The tnesh airenter-ing scoop 43, va'lve 4'4, and 'inlet passage "42;into portion 4I by mixing with partly unburned gases escaping from mouth 31 of pipe 33 completes their combustion. This constitutes portion .-39 xto :a small extent a jet propulsion chamber, the combustion occurring therein causing -a iiurth'er expansion of the gases and :creating .-a pressure which escapes out the mouth of sleeve 38 and in so doing creates a forward push in sleeve F38. In addition, the further combustion of the carbon A`monoxide included 'in the exhaust-gases -or oxidation thereof t carbon dioxide .isdesriable in .orderfto avoid the Apossibility ofaccidents .caused by inhaling it. The suction at :scoop 43 also `rtends `:to draw thercar .'forward. With valves 44 la'nd `5.5

.closedfand ^v alve 4F! open, the suction Yin portion 4| draws air throughadvance pipe 46, `.passage 35C, and inlet 45 thus cooling heater r35 and muf- -er ..34 yand .izetarding deterioration -of the latter. Suction now exists at mouth 48 and :tendsto'dra-w ftheicarsvforward.

With valves 44 and 41 closed and valve-5fopen, vairis :drawn throughfpipei .from .the :carinterior :andi-passes through .inlet opening 54 .intoheater 35, over fins .36 which .heat .-it, out .pipe 52 and into Ycircuits 5l and .5.3, .from .circuits 5I `and .E3 .into ,suction ,pipe 50 ,and throughropenin-g i9 into forward portion AAtl of -sleeve 3.8, the .suction .in ,portion d! .being the forcecreating .all theabove .air movement. .Themovement of air from the `carinterior.through heater .35 .also tends to .cool ymuiiler 3Q. The withdrawal .of .air from vthe -Car interior causes .a lowering of pressure `therein which is compensated by .an `increased .inward .seepage .of fresh air from outside, the .new air being readily .heated .by thecincuits 51,33, and the increased circulation .being most beneficial.

A third position of valve 5,5 .provides for air `for the heater 35 .to come .from outside the car instead of .-inside, but the advantage of :starting `with vwarm airis obvious. "Such third position `of valve 55 would iind'its use wherelthe car was passing through an area o'f Toul air and it was not wished to cause any seepage thereof Ainto the car body.'

The valves '44, "4T and '55 will preferably yJue 'interconnected and thermostatically controlled lso that any desired combination of the above :described effects may be obtained and 'thermostatically'maintained.

'It :isnoteworthy'that air and notexhaus't ,gases circulate in the heating .circuits 51 `'53 .so that =a leak in them would ,not .introduce exhaust gas `into the car interior.

The most :noteworthy feature .is vthat .all vthe l4 above benefits flow from energy which at present is being wasted for want of the within invention,

It is apparent that the illustrations shown above have been given by way of illustration and not by way of limitation and that the above described illustrations are subject to wide Variations and modifications, without departing from the scope or intent of the present invention. A11 of such variations and modifications are to be inrcluded within the scope of ithe'present invention.
